问题补充：
keep up to与keep up with的区别
答案：
Keep up with - 以中文来说,有紧紧跟随的意思.
例：Tim always trys to keep up with current events
Tim 总是试著了解时事
没有keep up to 这个东西 只有keep up
例:1.(使)不停止
Rain kept up all day.雨下了一整天
2.保持,继续
keep up the good work 继续有好表现
至於keep up (to date) with
这样写会更清楚:
keep up-to-date with the news
up-to-date为一个复合形容词!
keep up-to-date with something 就是随时掌握某事的最新消息或情况!
清楚了吗~======以下答案可供参考======
供参考答案1:
keep up 继续、坚持 keep up to+动词
keep up with 跟上 、不落后于人 keep up with +名词
供参考答案2:
keep up (to date) 没有keep up to 这个词组吧
keep up with 跟上
